Comparing two VectorDrawables fails in Kaspresso - Android

I'm trying to use Kaspresso for tests and I'm checking whether a view has a certain drawable with the method:

withId<KImageView>(R.id.criticalErrorImage) {
    hasDrawable(R.drawable.error_graphic)
}

With PNG works really well, while comparing the image stored in the imageView and restored and the VectorDrawable fails.

The file where the check is made is this one.

In particular this part of code:

            var expectedDrawable: Drawable? = drawable ?: getResourceDrawable(resId)?.mutate()

            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP && expectedDrawable != null) {
                expectedDrawable = DrawableCompat.wrap(expectedDrawable).mutate()
            }

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                tintColorId?.let { tintColorId ->
                    val tintColor = getResourceColor(tintColorId)
                    expectedDrawable?.apply {
                        setTintList(ColorStateList.valueOf(tintColor))
                        setTintMode(PorterDuff.Mode.SRC_IN)
                    }
                }
            }

            if (expectedDrawable == null) {
                return false
            }

            val convertDrawable = (imageView as ImageView).drawable.mutate()
            val bitmap = toBitmap?.invoke(convertDrawable) ?: convertDrawable.toBitmap()

            val otherBitmap = toBitmap?.invoke(expectedDrawable) ?: expectedDrawable.toBitmap()

The funny part is that it works if I'm setting the image through databinding, while it doesn't work if I set it in all other ways. Cannot understand why.

I've created a POC here: https://github.com/filnik/proof_of_concept

In particular, here is the test: https://github.com/filnik/proof_of_concept/blob/master/app/src/androidTest/java/com/neato/test/POCInstrumentationTest.kt

While here I dynamically set the image: https://github.com/filnik/proof_of_concept/blob/master/app/src/main/java/com/neato/test/FirstFragment.kt
